Hybrid tea rose plant named `Ruiliro`

ABSTRACT

A new variety of hybrid tea rose plant producing pink blend flowers.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety of roseplant of the hybrid tea rose class which was created by crossingundistributed, unnamed and unpatented seedlings as seed and pollenparents in The Netherlands. The varietal denomination of the new varietyis `Ruiliro`.

SUMMARY OF THE INVENTION

Among the novel characteristics possessed by this new variety whichdistinguish it from its parents and all other varieties of which I amaware are its attractive pink blend flowers.

Asexual reproduction by budding of the new variety as performed in TheNetherlands, shows that the foregoing and other distinguishingcharacteristics come true to form and are established and transmittedthrough succeeding propagations. The new variety has been reproducedthrough propagation by cuttings, grafting, budding and micropropagation.

BRIEF DESCRIPTION OF ILLUSTRATIONS

The accompanying two photographic illustrations show the new variety ofhybrid tea rose plant in color as true as it is reasonably possible toattain in color illustrations of this character.

The first illustration is a close up view of the bloom, peduncle, andfoliage.

The second illustration shows a new shoot, 1; compound 3-leaflet leaf,2; compound 5-leaflet leaf (partially cut-off), 3; compound 7-leafletleaf, 4; stem, 5; buds, 6 and 7; a flower about 1/3 to 1/2 open, 8; aflower fully open, 9; and flowering stems 10, 11, and 12, withreproductive organs displayed.

DESCRIPTION OF THE NEW VARIETY

The following is a detailed description of the new variety, with colorterminology in accordance with The Royal Horticultural Society ColourChart (R.H.S.C.C.) and horticultural terminology in accordance withstandard terminology used in UPOV-approved horticultural guidelines. Theterminology used in color descriptions herein refers to plate numbers inthe aforementioned color chart. Phenotypic expression may vary dependingupon growing conditions under different climate, soil, and cultivationconditions.

Parentage: Seed and pollen parents are unnamed seedlings.

Class: Hybrid Tea.

The following further horticultural description is based on observationsmade of specimens grown under glass in Quito, Ecuador.

FLOWER

Blooming habit: Nearly continuous.

A. Bud:

(1) Size.--About 5 cm long by about 2 to 4 cm wide, before sepals fall.About 5 to 6 cm long by about 4 cm wide, after sepals separate further.

(2) Form.--Ovate (shape of longitudinal section just before separationof sepals); urn-shaped after sepals part and petals begin to separate.

(3) Color.--Before sepals separate, white to near 56D with deeper tone,near 55C at petal edge becoming lighter until becoming near 4D at pointof petal attachment.

(4) Sepals.--One to three are longer than bud, most very foliaceous;near 147A on top surface, lighter, near 147B, on undersurface.

(5) Peduncle.--Long: Strength-erect, strong. Color near 138A to 138B.

B. Flower: Medium; viewed from side -- (a) upper part of fully openedflower, convex; (b) lower part of fully opened flower, concave.

(1) Size.--Average size when fully expanded -- about 7 to 9 cm at aboutfull open.

(2) Borne.--Singly, one to a stem.

(3) Form.--Mainly spiral imbricated, some outer petals have pointedapices, some inner petals ruffled and some roll under; somewhat recessedcenter in open bloom.

(4) Petalage.--Fully double, about 23.

(5) Color.--After sepals part and petals unfurl color of petal topsurface near edges appears near 56C to 56D with washing of deeper tones,near 62C to 62D, especially on outer petals, washing on outer mostpetals is between 62D and 62C. Petal undersurface exhibits samecoloration as top surface but with more matte appearance and outer edgeof outer most petals may show greenish edges. Color at point of petalattachment is near 62D to 3D to 4D. Overall tonality from a distance isunusual pink blend with light pink center.

(6) Peduncle.--Generally smooth.

(7) Fragrance.--Absent or weak.

(8) Length of stems.--About 60 cm to 100 cm.

Petals:

(1) Texture.--Crisp.

(2) Appearance.--Inside velvety and outside satiny.

(3) Form and size.--Broad, medium, medium undulation of margin.

(4) Arrangement.--Regularly arranged, imbricated.

(5) Petaloids.--Several, about 2 to 5.

(6) Lasting quality.--Long-lasting quality on plant (about 20 days) andafter cutting (about 14 days).

REPRODUCTIVE ORGANS

A. Stamens, filaments and anthers:

Arrangement and color.--Regularly arranged around styles; color offilaments -- white to pale yellow.

B. Pollen: Color -- near 19B to 19C.

C. Styles: Long, stigma above mouth of receptacle, white.

D. Stigmas: Yellow.

E. Hip: Pitcher-shaped; small seed vessel at petal fall.

PLANT

A. Form: Narrow, bushy, average disease resistance; height about 1.5 m,spread about 0.5 m.

B. Growth: Vigorous.

C. Foliage: Compound 3, 5 and 7 leaflets

(1) Size.--3-leaflet leaf, terminal leaflet about 7 cm long; 5-leafletleaf, terminal leaflet about 5 to 6 cm long; 7-leaflet leaf, terminalleaflet about 5 to 6 cm long.

(2) Quantity.--Abundant.

(3) Color.--Juvenile foliage -- top near 187A underside grey brown near187B; absent or weak anthocyanin coloration, (shoot about 20 cm long);mature top leaf color -- near 137A; undersurface near 138B.

(4) Shape.--Broad oval.

(5) Texture.--Upper side is medium glossy; underside is matte.

(6) Edge.--Serrate.

(7) Serration.--Serrulate, obtuse apices.

(8) Leaf stem.--Color -- near 138B.

(9) Stipules.--About 1.8 cm, green color same as leaves.
